摘要

群-亚群方案是晶体化学中一种使晶体结构系统化的有用工具，在复杂、孪晶和调制结构的x射线晶体学研究中是不可或缺的工具。同时，在所谓的Bärnighausen树中总结了许多上层建筑的变体。本数据库列出了有关晶体学/群理论工具和原始工作的相关文献，并给出了各自上层建筑的晶体学指纹(aristotype，空间群符号，Pearson代码和Wyckoff序列)的表格概述。

Bärnighausen Trees – A group–subgroup reference database

Abstract Group–subgroup schemes are a useful tool in crystal chemistry for systemizing crystal structures and they are an indispensable help during X-ray crystallographic studies of complex, twinned and modulated structures. Meanwhile many superstructure variants are summarized within so-called Bärnighausen trees. The present database lists relevant literature with respect to the crystallographic/group-theoretical tools and original work and gives a tabulated overview on the crystallographic fingerprints (aristotype, space group symbol, Pearson code and Wyckoff sequence) of the respective superstructures.

期刊介绍： Zeitschrift für Kristallographie – Crystalline Materials was founded in 1877 by Paul von Groth and is today one of the world’s oldest scientific journals. It offers a place for researchers to present results of their theoretical experimental crystallographic studies. The journal presents significant results on structures and on properties of organic/inorganic substances with crystalline character, periodically ordered, modulated or quasicrystalline on static and dynamic phenomena applying the various methods of diffraction, spectroscopy and microscopy.
